Over the past decade, driven by advances in educational theory and pressures for efficiency in the clinical environment, there has been a shift in surgical education and training towards enhanced simulation training. Microsurgery is a technical skill with a steep competency learning curve on which the clinical outcome greatly depends. This paper investigates the evidence for educational and tra...

Transfer in terms of skill maintenance and generalization is one of the key challenges in effective training design. Training design for critical military tasks often entails the use of simulations that are high on physical fidelity to minimize skill decrements that impede training transfer. Although this is an effective approach to resolving the transfer problem, it can be costly and inefficie...

The delivery of targeted temperature management (TTM) is recommended for cardiac arrest patients with specific initial rhythms after the return of spontaneous circulation. Some hospitals have established institutional TTM protocols based on national guidelines. Yet, successful implementation of an institutional TTM protocol depends on the nurses’ knowledge and skills. The study’s purpose was to...

Reduced-order modeling represents an attractive framework for accelerating computationally expensive reservoir simulation applications. In this paper we introduce and apply a reduced-order modeling approach for history matching. The method considered, trajectory piecewise linearization (TPWL), has been used previously for production optimization problems, where it has provided large computation...

OBJECTIVES/HYPOTHESIS We compare the behavior of expert surgeons operating on the "gold standard" of simulation-the cadaveric temporal bone-against a high-fidelity virtual reality (VR) simulation. We aim to determine whether expert behavior changes within the virtual environment and to understand how the fidelity of simulation affects users' behavior. STUDY DESIGN AND METHODS Five expert otol...

In recent years, digital reconstruction of cultural heritage provides an effective way of protecting historical relics, in which the modeling of surface reflection of historical heritage with high fidelity places a very important role. In this paper Gaussian process (GP) regression based approach is proposed to model the reflection properties of real materials, in which the simulation data gene...

A high-fidelity physics-based simulator for use in vascular interventional radiology (IR), interventional cardiology, and vascular surgery offers the ability to: Insert actual guidewires and catheters with realistic haptic feedback View simulated fluoroscopic images that show two-dimensional (2D) displays of three-dimensional (3D) anatomy Change the angle of "fluoroscopic" views using controls ...

Maritime operations involve complex tasks that must be taught through practical training. Using modern technologies offshore simulators can serve as realistic environment for training. The degree of immersiveness can be increased by replacing conventional input devices (keyboards, joysticks) with natural user interface (NUI) devices. This paper surveys different NUI technologies and advocates t...

In the summer of 1997, the Air Traffic Selection and Training (AT-SAT) High Fidelity Simulation Study was conducted at the FAA Academy in Oklahoma City, OK. The purpose of the study was to test the performance of 107 operational en route controllers during 2½ days of simulations. The performance of these controllers during the high-fidelity simulations was compared with their performance on two...
